What really hurts is when your aircraft gets grounded by an ex friend who has been working for the same company as I have been and suddenly gets a job with CASA. Next thing so called friend goes out of his way to inspect my aircraft in someone else's hangar me not being there so i receive latter of indefinate grounding due to not displaying Avgas only sticker next to fuel cap. Mind you he conducted my IFR renewal in same aircraft only months before he got his new appointment with no sticker near fuel cap.
It's just my experience with Gestapo that's all. I am still p###ed off.
